Answer:
Explanation:
The living parts of an environment are called biotic factor, nonliving are abiotic.
A large area characterized with a certain climate and species is a biome.
B. Cytoplasm, chloroplasts, and genes
C. Vacuoles, nucleus, and chromosomes
D. Chromosomes, chloroplasts, and vacuoles
The cell components that are most involved in determining the hair color of each sibling is gene, chromosomes, and nucleus. The correct option is A.
Genes are small spherical-shaped hereditary material that is present on chromosomes in a bead fashion. They contain the hereditary material of the organism. These are uncountable numbers of genes present in the chromosome.
Chromosomes are x shapes of hereditary material that are preset inside the nucleus. It is made up of DNA, genes, and proteins. Genetic characteristics of the genotype of an organism are unique because of unique genetic material, and this can be transferred to another generation from the first generation.
Therefore, the correct option is A. Gene, chromosomes, and nucleus.

Answer:
A
Explanation:C and D is automatically eliminated because humans don't have vacuoles (plants do) as well as B because humans don't have chloroplast
Answer ;
In summer, the green pigments or the chlorophyll are high, while in fall the chlorophyll lowers because there is less sunlight.
Explanation;
-The chlorophyll level in summer will be high because days are longer and there is more sunlight. The chlorophyll will lower in the fall because the fall has shorter days and less sunlight.
-Chlorophyll is a green pigment in green plants that absorbs sun light or energy from the sun that is required for the process of photosynthesis, the energy from sunlight is converted to chemical energy during the process.
ATP molecules is used to store and release energy like battery.
The principle chemical compound that cell uses to store and release energy is Adenosine triphosphate or ATP.
Adenosine triphosphate:
living things use chemical fuels as well, one of the principal chemical compounds that cells use to store and release energy is adenosine triphosphate ATP.
Three main parts:
ATP consists of
adrenine, a 5-carbon sugar called ribose and three phosphate groups.
A) Guaiacol
D) Tetraguaiacol
B) Peroxidase E) Hydrogen peroxide
C) buffer
Answer:
E) Hydrogen peroxide
Explanation:
Hydrogen peroxide is the substance that has a brown color and is detected by the spectrophotometer in our reaction.
2)Food choices come from what?
Answer:
1) Hunger, savor, appetite. Three main biological reasons why we eat. Also, the economic ability to pay for the food. And the fisical capability to go and buy food, to cook.

Savour is equal to enjoying. When people are not hungry they are happier. We choose what to eat depending on the look, taste, smell, texture. As sweets smell good, people consider them the most attractive food. Food is not just the source of nutrition, it is also the source of satisfaction.
